Tommy Hunter appeared close to coming off the disabled list, but the Rangers right-hander aggravated his groin injury during a minor-league rehab start yesterday.

Anthony Andro of the Fort Worth Star Telegramreports that he’s been diagnosed with a Grade 1 strain and will be shut down for 2-3 weeks, at which point Hunter will likely have to start his rehab stint over again.

Hunter, who originally injured his groin on March 24, had a 3.73 ERA and 68/33 K/BB ratio in 128 innings for the Rangers last season before going 0-2 with a 5.56 ERA in three playoff starts.
